Developing User Enhancement Modules in Adapter Engine Teched07 attender?

Question

Hi,
I am looking for the Java code of one of the hands on curses in the SAP Teched07.
The course was a XI/PI, <i>Developing User Enhancement Modules in the Adapter Engine</i>, and I need the Java code of the Java Bean that was used.
The name of the file is GetHostNameXXBean
If someone can help me i would appreciate it.
Thanks in advance.
Eduardo
